Transit routes are typically static in nature, i.e., the buses serve well-defined routes; this results in people living in away from the bus routes choose alternate transit modes such as private automotive vehicles resulting in ever-increasing traffic congestion. In the flex-transit mode, we reroute the buses to accommodate high travel demand areas away from the static routes considering its spatio-temporal variation. We perform clustering to identify several flex stops; these are stops not on the static routes, but with high travel demand around them. We divide the bus stops on the static routes into critical and non-critical bus stops; critical bus stops refer to transfer points, where people change bus routes to reach their destinations. In the existing static scheduling process, some slack time is provided at the end of each trip to account for any travel delays. Thus, the additional travel time incurred due to taking flexible routes is constrained to be less than the available slack time. We use the percent increase in travel demand to analyze the effectiveness of the rerouting process. The proposed methodology is demonstrated using real-world travel data for Route 7 operated by the Nashville Metropolitan Transit Authority (MTA).","PeriodicalId":284715,"journal":{"name":"Proceedings of the Fourth Workshop on International Science of Smart City Operations and Platforms Engineering","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127748175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper develops a spatiotemporal scenario data-driven decision solution for the path planning of multiple unmanned aircraft systems (UASs) in wind fields. The solution utilities offline operations, online operations and sptaiotemporal scenario data queries to provide an efficient path planning decision for multiple UASs. The solution features the use of similarity between spatiotemporal scenarios to retrieve offline decisions as the initial solution for online fine tuning, which significantly shortens the online decision time. A fast query algorithm that exploits the correlation of spatiotemporal scenarios is utilized in the decision framework to quickly retrieve the best offline decisions. The solution is demonstrated using simulation studies, and can be utilized in other decision applications where spaiotemporal environments play a crucial role in the decision process and the allowed decision time window is short.","PeriodicalId":284715,"journal":{"name":"Proceedings of the Fourth Workshop on International Science of Smart City Operations and Platforms Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129825856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted based on information from the National Institute of Standards and Technology (NIST) GCTC Action Clusters database and interactions with the project teams. A research process was developed and implemented, comprising the following three steps: (1) Investigate project descriptions created by the project leads on the NIST GCTC database and other public sources; (2) Gather additional input from volunteer GCTC collaborators; and (3) Identify a set of governing principles commonly shared by examples of GCTC projects. Based on the outcomes of this process, a set of common principles has been identified that enable designed-in security and privacy considerations among the projects: specific technology usage, implementation of a cybersecurity management process and framework, and cybersecurity expertise and public-private partnerships. Characteristics of planning and implementation of security and privacy considerations from four example GCTC projects are described and analyzed in detail to illustrate the process.","PeriodicalId":284715,"journal":{"name":"Proceedings of the Fourth Workshop on International Science of Smart City Operations and Platforms Engineering","volume":"92 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126128247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From unpredictable weather to hazardous roadways, there is a seemingly endless number of factors at play that can lead to vehicular accidents. Therefore, attempting to predict these accidents is a timely topic in today's research spectrum. The data used in this research consists of historical accident records from Hamilton County, Tennessee beginning in 2016 and continues to be updated daily, as well as the associated weather occurrences and roadway geometrics. To enhance heterogeneity a procedure was performed that generated non-accident traffic data based on our actual traffic accident data. This procedure is called negative sampling. These different data sets were combined and placed through a Multilayer Perceptron (MLP) machine learning model. The end results displayed a high collective correlation between accident occurrence and the various features considered in our proposed model, allowing us to predict with 77.5% accuracy where and when an accident will occur.","PeriodicalId":284715,"journal":{"name":"Proceedings of the Fourth Workshop on International Science of Smart City Operations and Platforms Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128679925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
